prosody fails when jitsi_meet_jicofo_password changes

[elijh]

When the variable jitsi_meet_jicofo_password is changed, the jicofo config is correctly updated, but prosody still uses the old password for focus. This command needs to be re-run:

prosodyctl register focus auth.{{ jitsi_meet_server_name }} {{ jitsi_meet_jicofo_password }}

Doing so will update the focus.dat file.
